Synthesis and Catalytic Performance of Large Zeolite Y Crystals
1. Introduction Zeolites have gained an irreplaceable role as catalysts in the refining industry. With a production capacity of 625·10 6 t in 2004, the fluid catalytic cracking process (FCC) represents the second most important heterogeneously catalyzed process [1]. As an active component, the catalyst of this process contains zeolite H-Y. Since a high-molecular feed is used, a detailed knowled...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Zeolite-like liquid crystals
Zeolites represent inorganic solid-state materials with porous structures of fascinating complexity. Recently, significant progress was made by reticular synthesis of related organic solid-state materials, such as metal-organic or covalent organic frameworks. Herein we go a step further and report the first example of a fluid honeycomb mimicking a zeolitic framework. In this unique self-assembl...
متن کاملMicrowave Assisted Synthesis of Nano Zeolite Seed for Synthesis Membrane and Investigation of its Permeation Properties for H2 Separation
MFI-type zeolite membranes (ZSM-5) were prepared on α-alumina tubular supports and tested for separation of H2/CO mixtures. The effect of pressure and temperature on H2 and CO flows and selectivity was investigated. The best results in this work were obtained with a ZSM-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with m...
